  • Properties and Behavior of Radionuclides

    For the purposes of this document, radionuclides should be considered to have properties similar to those of other heavy metals.This does not imply that all radionuclides are heavy metals, but that the majority of sites requiring remediation of radioactively contaminated materials are contaminated with radionuclides that have similar properties. Like metals, the contaminants of concern are ...

  • What do oil sands and shale gas have in common? Acute need for sustainable water management solutions

    The world’s appetite for fossil fuels is not abating anytime soon, and the alternatives fall short. Nuclear energy makes people uneasy, coal is perceived as not being that clean, hydroelectric requires massive capital outlays, solar is still improving and the wind just doesn’t always blow. For the foreseeable future, North Americans have embraced the idea that expanded production of ...

  • Mine backfill

    Mine backfill is defined as the material used to fill the cavities (i.e., stopes) created by underground mining. Backfilling can be a means to dispose of sludge and/ or tailings which may contain hazardous materials and to reduce surface environmental impacts by storing tailings underground. Alternately, backfilling with nonhazardous materials can allow for mining productivity improvements. To ...

  • A Study on the Costs of Improving the Management of Mining Waste

    1. Executive Summary Context, Scope and Priorities 1.1 This is the Final Report of a study into the costs of improving the management of mining waste. It was not carried out in isolation, but in parallel with a consultation process being run by the Directorate General for the Environment of the European Commission (DG ENV) and a technical review process coordinated by the European Integrated ...

  • GCW as a means of efficiently remediating contaminated groundwater

    With the conventional 'Pump & Treat' method, groundwater is normally extracted from one or several wells, cleaned above ground and disposed off to the either groundwater or surface water. Even when extraction and injection wells are combined, predominantly higher perme-able areas are preferentially penetrated and more fine-grained structures are circumflowed. The bulk of contaminants are ...

  • Skimmer with rolling stand helps prevent oily water discharge

    Despite continuous replacement and upgrading of fittings, it is difficult to entirely eliminate hydraulic and lubricating oil coming from machines during normal operations and maintenance activities. This oil ends up in different pits used to collect wastewater throughout the plant. Because of high oil content, city officials would not allow plant wastewater to enter the Longmont sanitary sewer ...
